- First, Open "File Explorer"

- Second, In the search bar, type in "C:\Users\{user}\AppData\Roaming\kingdom_rush_alliance"
(Make sure to change the "{user}" part with your own computer username, which can be found by going into. This PC > (C:) > Users > (should be the first one at the top)

- Lastly, open "settings", at the top you'll likely see "["fps"] = 60;" (simply change that "60" to your desired frame rate)

(Noted issues are, if you don't see "["fps"] = 60;" you need to enter the game, > Enter the settings, > Click to page 5, > make sure you have one of the two options selected for frame rate (60, 30) for it to appear in the settings folder.

(Reply to this thread for any help, can't promise it but I can try)
